AARON E. WOOLFE, OF CALGARY, ALBERTA, CANADA.

AUTOMOBILE RADIATOR.

Application filed December 27, 1923. Serial No. 683,024.

To all whom 'it may conce/m:

Be it known that I, Aaron E. Woonrn, a subject ot the King ot Great Britain, and a resident of Calgary, in the Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in' Automobile Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to radiators for automobiles or other uses where an air cooling lor water is desired.

In the construction of radiators for motor vehicles the art has been directed more to the provision of efficiency in cooling and economy of construction than toward rendering the water passages quickly and easily available for removal or repair.

It is the object ot' my invention to provide a radiator in which availability of the water tubes is Ltully provided, and to this end I have arranged the water tubes in a series of V-Shaped vertically extending rows, so that leaks in the tubes will either be taced to the iront or the back of a radiator core, and can be reached directly for repairs. To this end also, I have provided for spacers and heat convection fins in the form or' removable pieces, which may, if desired, be removable as a single unit.

The above and other objects to be noted, I accomplish by that certain construction land arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawing:

Figure 1 is a perspective view ot a radia tor core, illustrating several modiiications in the way of tubes and spacer devices.

.Figure 2 is a plan View illustrating the mode of spacing.

Figure 3 is a` perspective detail of a special Jform of corrugated metal water and air passage tube structure, which can be employed in my new radiator. y

It should be noted primarily, that the exact form of water tube in my radiator is a nonessential, since it is the tube arrangement whereby the main point of my invention is accomplished.

In Figure l is shown a radiator core, which will be set between two tanks, as in the usual motor vehicle radiator. To the left are shown water tubes 2, formed of folds of sheet metal to provide wide, thin tubes, the length of' the core. These tubes may be formed with corrugations or channels 2"L impressed in their sides, and are arranged in the core, when assembling the same, in V-shaped position with relation Vto each other, leaving at the apices ci' the several Vs, a space 3 for passage of air.

Instead of the wide flat tubes, I may en1- ploy a series of individual round tubes, as shown at 4, and these are arranged in a like V-shaped manner.

To make the core rigid, and provide heat convection tins, I provide tor the horizontal plates 5, having interspaced V-shaped projections 6, which lit the spaces between the lengthwise water tubes. The channels 2a are arranged so that the tongues or projec tions 6 will slide into them, and there may be as many plates 5 as there are channels in the water tubes.

In the case ot the rows ot round tubes 4, the projections 6 will be formed with notches Z to iit the walls oit' the tubes.

As indicated by the vertical straps or bars S, the assembly of plates 5 may be held together as a unit, and thrust into or withdrawn from the tube assembly, whenever desired to make the tubes available. Or else the plates 5 may be made separate, as indicated at the lett'hand side of Figure l.

rlhe plates 5 may be duplicated at the front and back oit the core, where the best rigidity ot the core is desired, as indicated in Figure 2, where the inner plate is indicated at 5a with projections 6u.

One way of torming the water tubes will be to corrugate a sheet et metal and bend it through the middle ot one corrugation as at 9, bringing the corrugation walls into contact at points l0, and into tubular tormation at points Il. In the act of folding the corrugated metal, the webs, where the walls contact, as at 'l0 may be punched out int-o holes 12. Thus a single sheet metal can be made up into thelequivalent of a series of vertical tubes el., with rad'ating and convection tins, through which iins currents of air may pass.

When a radiator` has been built up with the ends of the tubes inserted through proper slots in the top and bottom tanks, and the. plates 5 set in place at front and back, the repair man can take out the plates 5, and get at any tube he desires to repair a leak, or it the whole assembly is, soldered fast together, still every point of each tube will be available or application iof solder to patch up a leak, due to the `V-shapefl arrangement. Y

Having thus descnibel, lny Eiriyenfi-OII, what I claim as new and desire to secure by Letters Patent, is l. In a radiator core, a water passage elenient comprising a series of' water tubes extending lengthwise of the core, and arranged in V-shape, so as to expose the faces of the tubes at the front :and back of, the core.

2, In a radiator core, a Water passage element comprising a .series of' water tubes extending lengthwise' of .the core, and'` arranged in V-shape, so as to expose the faces ofjthe tubes at the front and" back lof the core, and spacers in the ltorna of plates havingffV-shaped projections adapted to en- ,fga-ge 'between the rows of, tnbGS 3. In a radiator core, a water passage elementtcoinprising a series of water tubes eX- extending lengthwise of the core., and arranged'in V-shapaso as to expose the faces of the tubes at the front and bacl; of the core, Vand spacers in 'the form plates lia-ving V-shapetl project-ions adapted to engage 'between the rows of tubes, and projecting inwardly from the liront and back 0f the Core AARON E.
